Abstract :
The radiation levels inside the experiments at the LHC will be very high. To ensure that all the electronics components used in the detectors will survive for the life the experiments, they will all be thoroughly tested for radiation hardness with neutrons and gammas. The CMS Electromagnetic Calorimeter has a dedicated neutron irradiator at the University of Minnesota to perform neutron irradiation of all electronic components that will be mounted on the detector. The irradiator uses 11.5 mg of 252Cf for the source, with a neutron flux of ≈ 9.5 × 1013 neutrons/h. In this paper the design, construction, and operations of the Californium Neutron Irradiator will be described.
